Abstract

본 발명은 공작기계의 헤드 회전장치에 관한 것으로, 크기가 크고 길이가 긴 공작물의 일측 단부를 커팅가공함과 동시에 상기 공작물의 단부에서 일정간격을 두고 상면, 저면, 좌측면 및 우측면의 구멍을 뚫는 드릴링 가공작업시 공작물을 회전시키지 않고, 상기 드릴 및 커터가 일체로 된 공작기계의 헤드를 회전하여 가면서 구멍을 뚫은 드릴링 가공작업을 행할 수 있는데 그 목적이 있으며, 그 구성은 베이스와, 이 베이스에 설치된 컬럼(1)과, 이 컬럼(1)에 설치되고 상·하 및 좌우운동이 가능한 아암(2)과, 이 아암(2)의 상부에 설치되고 주축에 전달수단(3)으로서 회전력을 전달하는 주축모터(4)와, 상기 주축모터(4)의 회전력에 의하여 구동하는 커터(51) 및 드릴(52)이 부착된 헤드(5)와, 이 헤드(5)를 공작물이 가공방향에 따라 회전시킬 수 있는 분할모터(6)로 구성한 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a head rotating device for a machine tool, and more particularly, to a head rotating device for a machine tool, which cuts one end of a large and long workpiece, and simultaneously drills holes in the upper surface, And it is an object of the present invention to provide a drilling machine which can drill a hole while rotating a head of a machine tool in which the drill and the cutter are integrated without rotating the workpiece during drilling processing, An arm 2 provided on the column 1 and capable of upward, downward, leftward and rightward movement, and an arm 2 provided on the arm 2 and transmitting a rotational force to the main shaft as a transmitting means 3 A head 5 with a cutter 51 and a drill 52 driven by the rotational force of the spindle motor 4 and a head 5 which is driven by the workpiece in the machining direction Split motor (6) .
